Which activity would the correctional nurse implement to address tertiary health promotion in individuals with long-term disease who are incarcerated?

Correct Answer: B

Rationale: The correct answer is B because administering medication for the treatment of hepatitis C falls under tertiary health promotion, which focuses on managing and treating long-term diseases to prevent complications. Teaching rescue inhaler use (A) is more related to secondary prevention. Advocating for low-sodium dietary options (C) and recommending physical therapy (D) are examples of primary prevention strategies.

Correct Answer: A

Rationale: The genetic code is redundant because different codons can specify the same amino acid. This redundancy provides a buffer against mutations, ensuring that a change in a single nucleotide does not always result in a change in the amino acid being coded for. This redundancy allows for error correction during translation, increasing the robustness of the genetic code. Choices B, C, and D are incorrect because the redundancy in the genetic code is primarily for ensuring accuracy and reliability in protein synthesis, not for developing new amino acids or non-coding signals.

Correct Answer: B

Rationale: The correct answer is B because differential mRNA splicing involves removing introns and joining exons from a single primary RNA transcript to create various mRNA isoforms. This process allows for the production of multiple proteins from a single gene, increasing genetic diversity. Choice A is incorrect because mRNA splicing does not involve creating a backup copy of DNA. Choice C is incorrect as mRNA carries the genetic code to the ribosomes, not the cytoplasm. Choice D is incorrect because ribosomes are not held together by mRNA splicing; they are composed of proteins and rRNA.

Correct Answer: B

Rationale: Correct Answer: B Rationale: 1. Mutations are random and constantly occurring in populations. 2. Deleterious alleles can arise from new mutations. 3. Selectively removing carriers won't prevent new mutations. 4. Thus, even if carriers are eliminated, new carriers will emerge, making it impossible to completely eradicate deleterious alleles. 5. This perpetual nature of mutations undermines any effort to eliminate deleterious alleles effectively.

Correct Answer: B

Rationale: The correct answer is B because triploidy involves the presence of one extra set of haploid chromosomes, resulting in a total of three sets (3n), while tetraploidy involves two extra sets, resulting in a total of four sets (4n). This leads to abnormal chromosome numbers in cells. Choice A is incorrect because triploidy and tetraploidy do not refer to specific chromosomes but to the number of whole sets of chromosomes. Choice C is incorrect as triploidy and tetraploidy do not directly relate to sexual characteristics. Choice D is incorrect as triploidy and tetraploidy are not caused by chromosome breakage due to radiation but rather by errors in cell division during fertilization.
